Tunnel diode flip flop circuit for providing complementary and symmetrical outputs

Claim 1

A BISTABLE CIRCUIT COMPRISING A SOURCE OF SUBSTANTIALLY CONSTANT CURRENT, FIRST AND SECOND CURRENT PATHS COUPLED IN PARALLEL WITH SAID CURRENT SOURCE, EACH OF SAID FIRST AND SECOND PATHS INCLUDING A SERIES COUPLED RESISTOR, TUNNEL DIODE AND SWITCHING DIODE, FIRST AND SECOND INPUT TERMINALS COUPLED BETWEEN SAID SWITCHING DIODE AND SAID TUNNEL DIODE OF SAID RESPECTIVE FIRST AND SECOND PATHS, FIRST AND SECOND OUTPUT TERMINALS COUPLED BETWEEN SAID RESISTOR AND SAID TUNNEL DIODE OF SAID RESPECTIVE FIRST AND SECOND PATHS, SAID TUNNEL DIODES EACH HAVING FIRST AND SECOND STABLE STATES RESPECTIVELY PROVIDING A LOW VOLTAGE DROP WITH A HIGH CURRENT FLOW AND PROVIDING A HIGH VOLTAGE DROP WITH A LOW CURRENT FLOW, SAID TUNNEL DIODES RESPONDING TO SAID SUBSTANTIALLY CONSTANT CURRENT TO EACH ASSUME A DIFFERENT ONE OF SAID STABLE FIRST AND SECOND STATES, WHEREBY IN RESPONSE TO A PULSE APPLIED TO SAID FIRST OR SECOND TERMINAL AND TO THE TUNNEL DIODE IN THE FIRST STATE, SAID TUNNEL DIODE IN THE FIRST STATE IS TRIGGERED TO ITS SECOND STATE TO CHANGE THE CURRENT THERETHROUGH SO AS TO TRIGGER THE TUNNEL DIODE IN THE SECOND STATE TO ITS FIRST STATE, THUS APPLYING CORRESPONDING VOLTAGES TO SAID OUTPUT TERMINALS.
